Ariz. Admin. Code § 18-9-A202

Current through Register Vol. 30, No. 50, December 13, 2024

Section R18-9-A202 - Technical Requirements

A. Except as specified in R18-9-A201(C)(1), an applicant shall, as required under R18-9-A201(B)(4), submit the following technical information as attachments to the individual permit application:

1. A topographic map, or other appropriate map approved by the Department, of the facility location and contiguous land area showing the known use of adjacent properties, all known water well locations found within one-half mile of the facility, and a description of well construction details and well uses, if available;

2. A facility site plan showing all known property lines, structures, water wells, injection wells, drywells and their uses, topography, and the location of points of discharge. The facility site plan shall include all known borings. If the Department determines that borings are numerous, the applicant shall satisfy this requirement with a narrative description of the number and location of the borings;

3. The facility design documents indicating proposed or as-built design details and proposed or as-built configuration of basins, ponds, waste storage areas, drainage diversion features, or other engineered elements of the facility affecting discharge. When formal as-built plan submittals are not available, the applicant shall provide documentation sufficient to allow evaluation of those elements of the facility affecting discharge, following the demonstration requirements of A.R.S. § 49-243(B). An applicant seeking an Aquifer Protection Permit for a sewage treatment facility satisfies the requirements of this subsection by submitting the documents required in R18-9-B202 and R18-9-B203;

4. A summary of the known past facility discharge activities and the proposed facility discharge activities indicating all of the following:

a. The chemical, biological, and physical characteristics of the discharge;

b. The rate, volume, and frequency of the discharge for each facility; and

c. The location of the discharge and a map outlining the pollutant management area described in A.R.S. § 49-244(1);

5. A description of the BADCT employed in the facility, including:

a. A statement of the technology, processes, operating methods, or other alternatives proposed to meet the requirements of A.R.S. § 49-243(B), (G), or (P), as applicable. The statement shall describe:

i. The alternative discharge control measures considered,

ii. The technical and economic advantages and disadvantages of each alternative, and

iii. The justification for selection or rejection of each alternative;

b. An evaluation of each alternative discharge control technology relative to the amount of discharge reduction achievable, site-specific hydrologic and geologic characteristics, other environmental impacts, and water conservation or augmentation;

c. For a new facility, an industry-wide evaluation of the economic impact of implementation of each alternative discharge control technology;

d. For an existing facility, a statement reflecting the consideration of factors listed in A.R.S. § 49-243(B)(1)(a) through (h);

e. A sewage treatment facility meeting the BADCT requirements under Article 2, Part B of this Chapter satisfies the requirements under subsections (A)(5)(a) through (d).

6. Proposed points of compliance for the facility based on A.R.S. § 49-244. An applicant shall demonstrate that:

a. The facility will not cause or contribute to a violation of an Aquifer Water Quality Standard at the proposed point of compliance; or

b. If an Aquifer Water Quality Standard for a pollutant is exceeded in an aquifer at the time of permit issuance, no additional degradation of the aquifer relative to that pollutant and determined at the proposed point of compliance will occur as a result of the discharge from the proposed facility. In this case, the applicant shall submit an Ambient Groundwater Monitoring Report that includes:

i. Data from eight or more rounds of ambient groundwater samples collected to represent groundwater quality at the proposed points of compliance, and

ii. An AQL proposal for each pollutant that exceeds an Aquifer Water Quality Standard;

7. A contingency plan that meets the requirements of R18-9-A204;

8. A hydrogeologic study that defines the discharge impact area for the expected duration of the facility. The Department may allow the applicant to submit an abbreviated hydrogeologic study or, if warranted, no hydrogeologic study, based upon the quantity and characteristics of the pollutants discharged, the methods of disposal, and the site conditions. The applicant may include information from a previous study of the affected area to meet a requirement of the hydrogeologic study, if the previous study accurately represents current hydrogeologic conditions.

a. The hydrogeologic study shall demonstrate:

i. That the facility will not cause or contribute to a violation of an Aquifer Water Quality Standard at the applicable point of compliance; or

ii. If an Aquifer Water Quality Standard for a pollutant is exceeded in an aquifer at the time of permit issuance, that no additional degradation of the aquifer relative to that pollutant and determined at the applicable point of compliance will occur as a result of the discharge from the proposed facility;

b. Based on the quantity and characteristics of pollutants discharged, methods of disposal, and site conditions, the Department may require the applicant to provide:

i. A description of the surface and subsurface geology, including a description of all borings;

ii. The location of any perennial, intermittent, or ephemeral surface water bodies;

iii. The characteristics of the aquifer and geologic units with limited permeability, including depth, hydraulic conductivity, and transmissivity;

iv. The rate, volume, and direction of surface water and groundwater flow, including hydrographs, if available, and equipotential maps;

v. The precise location or estimate of the location of the 100-year flood plain and an assessment of the 100-year flood surface flow and potential impacts on the facility;

vi. Documentation of the existing quality of the water in the aquifers underlying the site, including, where available, the method of analysis, quality assurance, and quality control procedures associated with the documentation;

vii. Documentation of the extent and degree of any known soil contamination at the site;

viii. An assessment of the potential of the discharge to cause the leaching of pollutants from surface soils or vadose materials;

ix. For an underground water storage facility, an assessment of the potential of the discharge to cause the leaching of pollutants from surface soils or vadose materials or cause the migration of contaminated groundwater;

x. Any changes in the water quality expected because of the discharge;

xi. A description of any expected changes in the elevation or flow directions of the groundwater expected to be caused by the facility;

xii. A map of the facility's discharge impact area; or

xiii. The criteria and methodologies used to determine the discharge impact area.

9. A detailed proposal indicating the alert levels, discharge limitations, monitoring requirements, compliance schedules, and temporary cessation or plans that the applicant will use to satisfy the requirements of A.R.S. Title 49, Chapter 2, Article 3, and Articles 1 and 2 of this Chapter;

10. Closure and post-closure strategies or plans; and

11. Any other relevant information required by the Department to determine whether to issue a permit.

B. An applicant shall demonstrate the ability to maintain the technical capability necessary to carry out the terms of the individual permit, including a demonstration that a certified operator will operate the facility if a certified operator is required under 18 A.A.C. 5. The applicant shall make the demonstration by submitting the following information for each person principally responsible for designing, constructing, or operating the facility:

1. Pertinent licenses or certifications held by the person;

2. Professional training relevant to the design, construction, or operation of the facility; and

3. Work experience relevant to the design, construction, or operation of the facility.
